TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALBERT STUQKENRATH, of the city, county, and State of New York, have invented a new and useful-Improvement in the Mode of Operating Steam or other Cut-Oli's, at the same time showing the number of horse-power, Sto., by means of a graduated dial and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which are lettered to correspond with and constitute a part of the specication.

In order that the public may fully understand the nature of my improved invention, and those skilled in the construction and operation of the steam engine be enabled to construct and use the same,l I will describe it as follows, to wit: i l

Figure 1 is a perspective drawing of a vertical section of the `steam chest which contains the cut-olf, and my improved mode of operating the same.

Figure 2 is a perspective drawing of a forked lever, L, having four prongs or projectingl points, 1 2 3 4, which sustain and adjust the movable ring, R, by means of arms, d d.

Figure 3 is aperspective .drawing of the steam chest S, and graduated dial-plate D, showing the connectingrod or lever, e e', and governor, f.

My invention does not consist in constructing a cut-off for steam engines, nor of the arrangement of a right and left-handed screw to operate the cut-off valve by means of dogs and sprin'gsf neither does it consist in adjusting the cut-o` from the outer side of the steam chest S, nor attaching an index to the end of the cut-oli` valve-rod, n,.as they are fully set forth in my application for .a patent allowed May the first, 1866, and numbered' 54,439; but the novelty of my present improvement does consist in the construction and arrangement of alever, L, having four prongs or projecting points, 1 2 3 4, by which means it (the lever) operates the adjustable or movable ring R, which recprocates upon the rod n, when acted upon by the lever L, whose fulcrum, F, runs `transversely across andis secured to the sides of the steam chest S, or otherwise. The lever Lis operated by the action of the mainvalve, by which means the desired motion is given to the cut-olf.

The superiority of the above-stated improvement over the dogs, andi springs, and other appliances for operating the cut-oii` valves of a steam or other engine, is that the pronged lever L is not a'ected by superheated steam, as is the case with the springs that operate the falls (or dogs at the same time I believe a more uniform action is produced and retained by means of the lever L and movable ring R, than by any other device employed for such purposes; therefore, I

What I claim as novel and'useful, and what I wish to'secure by Letters Patent of the United States of North America, is-

The lever L, adjustable ring R, constructed substantially' as and for the purpose set lforth and shown in the accompanying drawings.

I also claim the combination of the pronged lever L, adjustable ring R, levers u, and index of the graduated dialD, substantially as set forth.

In testimony whereof I hereunto subscribe my name in the presence of two witnesses.

ALBERT STUCKENRATH.
